R-Walker Selfsustaining Free Energy bike from Mexico

Stefan this sounds like they use a buck converter to generate low voltage for logic, say if they have an Arduino or some other microcontroller board running off 5V or 3.3V, and a boost converter to run the electric motor.

So, possibly a Joule Thief for an electric bike then?  But, if they are simply stepping up the voltage and using pulses, that would not account
for converting 36 watts into 1500 watts right?  Obviously still some translation and communications issues here.  Also, it sounds like they want to file a patent on this so, exact details might be withheld anyway.

All in all, it is still very interesting, and puzzling at the same time.

Good info Stefan. It is a little hard to determine if he is talking completely about the electric drive motor,
or also referring to the dynamo as an electric motor as well. Maybe he would only refer to the dynamo
generator as a dynamo however. It may well be that he made modifications to both the electric drive motor
and the dynamo generator, as he previously mentioned in an interview about spending time on the dynamo, I believe.

All the best...

I asked then:

Yes, I see, the super capacitors have only a limited voltage.
But how do you increase the amperes ?

Answer:

Aumentando frecuencias constantes. Sin tomar sobrantes

Increasing constant frequencies. Without taking leftovers

Suppose they have a 3Ah 12V battery.  That could be misinterpreted as a 36W battery when it is a 36Wh battery.  There is a huge difference.  When dealing with batteries, particularly high C rate batteries like NiCd, NiMH, or Li-ion, C rates of over 50: full discharge in just over one minute are possible with some cells.  A 36Wh battery discharged at a C50 rate delivers 1800W for that short time.

However, here they have a couple of 1.5F super capacitors.  For milliseconds those capacitors can deliver rather high power.  But they have only about 100J to give before they are fully depleted.

Did you increase the frequency in the generator or in the motor ?

Answer:

Ambos

In both.
